This error can be frustrating as it prevents you from uploading files to Google Drive, which may have important work or personal data. In this guide, we will walk you through the steps to resolve this issue.

💡 Why You Are Getting This Error

  • The primary reason for this error is that the service account's credentials are not properly set up or configured. This can occur when the OAuth2 client ID and secret key are not correctly added to the Google Library, or if the service account has incorrect permissions.

🛠️ Step-by-Step Verified Fixes

Resolving the Issue by Re-Configuring OAuth2 Client ID and Secret Key

  1. Step 1: Go back to the Google Library and ensure that you have added the correct service account's OAuth2 client ID and secret key. Make sure to select the correct project and service account.
  2. Step 2: Verify that the OAuth2 client ID is in the 'Web application' or 'Desktop application' mode, depending on your use case.
  3. Step 3: If using a service account, ensure that it has been granted the necessary permissions to access Google Drive.

Resolving the Issue by Updating Token Expiration Date

  1. Step 1: Check the token expiration date of the service account's credentials. You can do this by going to the Google Cloud Console and navigating to the IAM & Admin > Service accounts > [Service Account Name].
  2. Step 2: Update the token expiration date if necessary, or generate a new token by clicking on the 'Refresh' button.
  3. Step 3: After updating the token expiration date, try uploading files to Google Drive again using the client token.

💡 Conclusion

By following these steps, you should be able to resolve the error and successfully upload files to Google Drive. Remember to regularly check your OAuth2 client ID and secret key for any changes or updates, and update the token expiration date as needed.
